This dictionary provides extensive documentation
of the Ch'ol language (spoken in northern Chiapas, Mexico),
which is considered crucial for the deciphering of Mayan glyphs and inscriptions.

The second edition (1996) provided many improvements over the first (1978) edition.
The information it contains is more accessible because everything in the Ch'ol-Spanish section
is also in the Spanish-Ch'ol section, and vice versa.
Dialectal variants are identified;
the grammar notes and bibliography have been updated;
the flora and fauna appendix now includes all items in the body of the dictionary.
New appendices, drawn from the dictionary, have been added:
expressions that refer to time,
words used to indicate size,
an extensive list of grammatical and semantic morphemes,
and a list of place names with maps of the Ch'ol area in Chiapas.
